Technical Field

The invention belongs to the technical field of decorative materials, and particularly relates to a heat-insulating and noise-reducing cloth-coated wallboard.

Background

The cloth-coated wallboard is also called as a cloth art wallboard, a wall cloth process is added on the integrated wallboard, so that the decorative effect is more warm and beautiful, and compared with the traditional wallpaper and wall paint, the cloth-coated wallboard has the advantages of dust-free installation, health, environmental protection and the like. The integrated wallboard is a novel, environment-friendly and quick decoration material developed by modern science and technology, the second generation is developed at present, the material is mainly made of bamboo fiber, crystal powder, high-polymer waterproof and fireproof materials and the like after being subjected to high pressure, and the surface of the integrated wallboard is coated with high-temperature film or is coated with a roller coating process, so that the integrated wallboard has rich colors and patterns like wallpaper, and the stereoscopic impression can be increased.

In recent years, with the continuous improvement of living standards of people, the requirements on living conditions are improved, with the development of building energy conservation in China, more and more buildings use the wall boards as internal decorative materials for playing the functions of heat preservation, noise reduction, fire prevention and the like, compared with the defect of high cost caused by the fact that the traditional wall cloth is processed by adopting a nanotechnology to realize the functions, the cloth-coated wall board has more play spaces, and then products with good heat insulation and noise reduction effects are obtained by using lower manufacturing cost and more convenient manufacturing procedures, so that the use requirements of people are met.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a heat-insulating and noise-reducing cloth-coated wallboard.

In order to achieve the purpose, the invention adopts the following technical scheme:

a heat-insulating and noise-reducing cloth-coated wallboard comprises a base plate, fiber cloth attached to one side, close to a wall surface, of the base plate, and decorative cloth attached to one side, far away from the wall surface, of the base plate;

the side, close to the substrate, of the fiber cloth is coated with viscous slurry, and the viscous slurry is ultraviolet curing resin glue solution and comprises glass hollow microspheres with the average particle size of 60-135 mu m and hollow silicon dioxide microspheres with the average particle size of 5-30 mu m.

In the invention, in order to realize better heat insulation and noise reduction effects, the viscous slurry needs to form a certain thickness on the side of the substrate close to the wall surface, so the viscosity of the viscous slurry is necessarily kept to a smaller degree, and the fluidity of the slurry with smaller viscosity is poorer, so that a uniform coating surface is difficult to form. Further, the inventor finds that the fiber cloth layer is arranged unintentionally, so that the rubbing of the side, which is not provided with the decorative cloth, of the traditional cloth-coated wallboard to the side provided with the decorative cloth is avoided, that is, the final finished product does not need to be stacked in a staggered manner intentionally, the labor intensity of workers is reduced, and the production efficiency is improved.

In the invention, in order to improve the heat insulation and noise reduction effects of the cloth-coated wallboard, the substrate is provided with two layers of cavity structures arranged along the thickness direction of the board, each layer of cavity structure is provided with cavities arranged at intervals, and the width of each cavity is 0.5-2 cm. Through the arrangement of the structure, the whole weight of the cloth-coated wallboard is reduced, the manufacturing cost of a product is reduced, and the subsequent installation operation is facilitated.

According to the invention, the fiber cloth is selected from one of carbon fiber cloth, glass fiber cloth, basalt fiber cloth and aramid fiber cloth. In particular, carbon fiber cloth is preferable. Further, the specification of the fiber cloth is preferably 3K, 6K, 12K or 24K. The meaning represented by "K" is known to those skilled in the art, and specifically refers to the number of fiber filaments contained in one fiber bundle in the fiber cloth. For example, 1K means that a fiber bundle contains 1000 filaments. In addition, the thickness of the fiber cloth can be selected according to actual requirements, the thicker fiber cloth has better noise absorption effect after being attached to the wall surface, and the thickness of the fiber cloth is selected to be 0.1-0.5mm based on the consideration of cost.

According to the invention, the viscous slurry comprises the following components in percentage by mass: 30-40% of ultraviolet curing resin glue, 2.5-5% of glass hollow microspheres, 10-20% of hollow silicon dioxide microspheres, 0.1-1% of dispersing agent and the balance of solvent. In the present invention, by controlling the contents of the components in the viscous paste within the above ranges, it is ensured that the formed viscous paste has a suitable viscosity, thereby forming a suitable thickness on the fiber cloth.

Specifically, the ultraviolet curing resin glue is one or a combination of at least two of polyurethane glue, epoxy resin glue, acrylate glue, organic silicon glue and polyester resin glue. Furthermore, the ultraviolet curing resin glue is preferably acrylate glue, specifically, such as WJ produced by Wanjun chemical new material science and technology Co., Ltd; the solid content of the acrylate glue is 50%.

The dispersing agent is one of polysiloxane copolymer, polyether polymer and high molecular weight block copolymer containing pigment affinity group. Furthermore, the dispersant is preferably a high molecular weight block copolymer containing pigment affinity groups, such as BYK-160, BYK-161, BYK-162 or BYK-163 from Bick chemical, Germany.

The solvent is one or more of ethyl acetate, butanone and butyl acetate.

In the specific forming procedure, firstly preparing viscous slurry, specifically, weighing ultraviolet curing resin glue, glass hollow microspheres, hollow silica microspheres, a dispersing agent and a solvent according to the proportion, and uniformly mixing by using a stirrer; coating the prepared viscous slurry on a fiber cloth, laminating the fiber cloth on a substrate, rolling, and irradiating the fiber cloth layer by using a high-pressure mercury lamp at the energy of 1000mj/cm2 to harden the UV glue; finally, decorative cloth is covered on the other side of the base plate, and a final finished product of the cloth-covered wallboard is obtained.

Compared with the prior art, the invention has the following technical effects:

according to the cloth-coated wallboard provided by the invention, the fiber cloth is arranged on one side of the cloth-coated wallboard close to the wall surface, and is matched with the viscous slurry coated on one side of the fiber cloth close to the substrate, so that a good adhesion effect is ensured, and the glass hollow microspheres with large particle sizes and the hollow silica microspheres with small particle sizes filled in the viscous slurry realize a good heat insulation effect.

Additional features and advantages of the invention will be set forth in the detailed description which follows.
